SPECIFICATION forming part of Letters Patent No. 650,547, dated May 29, 1900.

Application filed October '7, 1899. Serial No. 732,951. (No model.)

To all whom it may concern:

Be it known that I, DAVID SINCOCK, a resident of Clyde Park, in the county of Park and State of Montana, have invented certain new and useful Improvements in Mowing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and to use the same.

My invention relates to an improvement in mowing-machines, one object of the invention beingto provide improved means for reciprocating the cutter of a mowing-machine.

x 5 A further object is to improve the construction described and claimed in my Patent No. 632,375, granted tome September 5, 1899, for an improvement in mowing-machines.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is 2 5 a view illustrating my improvements, and

Figs. 2, 3, and 4 are enlarged views of details.

A represents the frame of my improved mowing-machine, and B the flexible shaft transmitting motion to my improved camwheel 0. The camwheel O is mounted on the cutter-bar 2, and one end of the cutter 3 is disposed beneath the cam-wheel O. A block 4, having a recess a, is secured on the upper face of the cutter-bar, and the end walls of said recess are curved, as shown at 5 in Fig. 3, to conform to antifriction-rollers 6, which are loosely disposed in the recess l. The

portions 7 of the block at each side of the rollers are made to embrace the rollers sufficiently to prevent the escape of said rollers. A plate 8 is secured on each block and overlaps the rollers 6 to e'lfectually prevent displacement of said rollers.

The flange 9 on the wheel is made sinuous, as shown, and the angular portions of the flange are made thicker, so as to remain in contact with both the rollers at all times, and hence prevent the jar and jolting which would otherwise occur and which would result in great damage to all parts of the machine and at the same time so greatly decrease the power necessary to draw the mowing-machine along the ground.

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention,

and hence I would have it understood that I do not wish to limit myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a mowing-machine, the combination with the cut-ter-bar, of a wheel mounted over one end thereof and having a sinuous peripheral flange thicker at the angles than at the intermediate portions, a block secured to the cutter-bar under said wheel, said block having a recess having curved end walls, rollers mounted freely in the respective ends of said recess, and plates secured upon saidblock and projecting partially over said rollers, the 7 5 sinuous flange on the wheel passing transversely through the recess in the block and in constant engagement with both of said rollers.

In testimony whereof I have signed this specification in the presence of two subscrib- 8o ing witnesses.

DAVID SINOOOK.
